Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541164, here are decompositions:
- 3 + 31541161 = 31541164
- 23 + 31541141 = 31541164
- 47 + 31541117 = 31541164
- 113 + 31541051 = 31541164
- 173 + 31540991 = 31541164
- 293 + 31540871 = 31541164
- 521 + 31540643 = 31541164
- 821 + 31540343 = 31541164
Showing the first eight; more decompositions exist.
